Would a ticking that gets louder and faster as you accelerate be the lifters? I checked in one of the manuals (from pep boys) and it said a ticking could be many things including a pinhole on/in about three things (including the piston) or it could be the piston hitting, and about 6 other things. Also, what do you make of the oil pressure spiking up (to off the guage) when idling and driving. It's only at normal pressure about half the time. I need a new Ideler motor (likes to rev and fall between 500-1000 RPM in neutral) and it will spike and fall alot as it does this.
